Women who develop preeclampsia during pregnancy are more likely to develop certain dangerous autoantibodies than women with normal pregnancies, and these autoantibodies are still present two years after childbirth in about 20 percent of women who had the disorder, scientists from the University of Pittsburgh report in the March issue of Hypertension, the journal of the American Heart Association.
Adult men who grew up in one-parent households are more likely to have been abused as children, according to a study conducted at the University of Pennsylvania?s School of Medicine.
Does God or some other type of transcendent entity answer prayer? The answer, according to a new Arizona State University study published in the March journal Research on Social Work Practice, is ?yes.?
Unlike most of our sensory systems that detect only one type of stimuli, our sense of smell works double duty, detecting both chemical and mechanical stimuli to improve how we smell. This finding, plus the fact that both types of stimuli produce reaction in olfactory nerve cells, which control how our brain perceives what we smell, explains why we sniff to smell something, and why our sense of smell is synchronized with inhaling.
Inflammatory bowel diseases, such as Crohn?s disease and Ulcerative Colitis, severely impair the lives of more than four million people worldwide. The development of effective therapies against these diseases requires an understanding of their underlying molecular mechanisms.
A new method for analysis of retroviral proteins gives new opportunities to the development of novel retardants for HIV/Aids. The study, which was published in the March issue of PLoS Computational Biology, shows how to in a very exact way analyze the interaction of drug targets with small molecules.
Researchers at the University of Pennsylvania School of Medicine are harnessing two new, non-invasive techniques to look more closely inside the working lungs – leading to early detection of diseases, like emphysema, before it becomes evident in other modes of imaging.
In order to differentiate and specialize, stem cells require very specific environmental cues in a very specific order, and scientists have so far been unable to prod them to go through each of the necessary steps. But now, for the first time, a study in mice by Rockefeller University scientists shows that embryonic stem cells implanted in the brain appear to develop into fully differentiated granule neurons, the most plentiful neuron in the cerebellum.
What if there was an outbreak of avian flu in Pennsylvania and public health officials had to institute quarantines to stop the spread of the deadly disease? How would the state?s courts respond if someone resisted or challenged a quarantine in court, particularly since no Pennsylvania case law, statute or court ruling has ever established specifically who can petition a court to institute a quarantine or what procedures to follow to do so?
Medically treating post-partum depression may not be enough to improve a mother?s relationship with her baby, and is only part of the equation, according to a new study done in part by the University of Alberta.
